Usain Bolt wants to 'push barriers'

Jamaican sprinter Usain Bolt wants to continue to "push barriers" after his success at the London Olympics.

Despite being under immense pressure, Bolt stormed to victory and successfully defended his 100m and 200m Olympic crown before adding a third gold medal as Jamaica set a new world record in the 4x100m relay.

After finishing as a triple Olympic champion for the second consecutive games, Bolt insists that he isn't ready to call it a day yet.

"I like to push the barriers," said Bolt. "I like to do things people have never done before because it sets you apart from everybody else.

"The rest of my races are for my fans. It will be the first time running as a living legend, so I'm going to see my fans, wave to them, do some crazy stuff. It's going to be fun."

Bolt holds the world records in both the 100m and 200m.
